Also, these numbers seem to have been pulled somewhere in thin air.
Must be. Crypto is one of the hardest asset classes to value, so it all comes down to personal bias in the end.
If you have a strong dislike towards certain coins, you will automatically value them much lower. In my case that means BCash's 'fair' value is between shouldn't exist and a buck. Obviously, that also means that coins you like will be granted a much higher 'fair' valuation.
In the end, the latest market rates are what people want to pay for them, so that's the only form of 'fair' value crypto can have. If people don't want to pay $3700 for Bitcoin anymore, it will drop to levels they are comfortable buying in again, and that applies to every crypto currency. Money speaks for itself, thoughts about crypto being worth more doesn't.
